Are you running the XEN kernel? Your screenshot mentions the GENERIC kernel.

I just booted the install CD.
As I said with the 7.2 installation cd it works(hvm).
However with the 8.0 it doesn't. I thought there was support for this from 8.0 included into the kernel... or am I confusing this with something else? (http://blog.xen.org/index.php/2009/1...ntal-xen-domu/)

Is there any other kernel included that I can use?

And are there any specific things I need then to have in my Xen VM config?

You said you followed the instructions, but instruction #7 requires you to build the XEN kernel, and instruction #11 tells you to boot it. Or are you encountering errors even before you get to that stage?

I first updated my already running 7.2-RELEASE system to 8.0-RELEASE.
When loading into the new kernel I got a kernel panic.

So I tried with a new VM (as in the link I provided).
I got to #5. So at the bootup there, I got a kernel panic.

I can't install a normal 8.0-RELEASE system.

Do note that I have not svm (AMD-V).
But as my previous install works (which was 7.2) I don't think this really matters.

Which kernel? GENERIC or XEN? You need to build and install the XEN kernel, not GENERIC.

I gave up on Xen about a year ago. Haven't tested it since then. However, FreeBSD 8.0 does work in KVM, which uses SVM, so it should work in Xen.

All 3rd-generation Opterons have 4-digit model numbers. All 3rd-generation Opterons include SVM support. Thus, you definitely have SVM support in the CPU. Whether or not it's enabled in the BIOS, though?

However, it is physically impossible to run hardware-assisted virtualisation (HVM) without SVM enabled.

This brings me back to my earlier posts (sorry to keep whining about this ): why did it then work with 7.2? I am pretty sure it uses GENERIC kernel(can't check atm).

OK... so I should keep trying and eventually it should work

Thus, you do have SVM support, and you do have it enabled.

hehe, thanks for clearing that out. Had googled and found that svm should be in the /proc/cpuinfo features list.

Now I tried following things:
Installed a FreeBSD 8.0-RELEASE in VMware.
After that recompiled the kernel with xen support.
Copied the generated "kernel" file to my Xen dom0. (this seemed strange to me but followed the steps in the link put above)

Now I created an image of that bsd install with mfsbsd.
Copied the generated image(I am not sure if I have to do anything special to have a special kernel on the domU image) to my dom0.

After that I specified this mfsbsd in my domU config
This is the config:
